I had the scrapbooks that took this size and couldn't find! them locally. Looking online through Google, I found these and they are PERFECT thus allowing me to finish my projects!!!
I only wish I could buy another 6X6 scrapbook. They are not available anywhere now.

The refill pages were exactly what I needed. Couldn't find 6x6 anywhere else. Able to add pages to my book instead of buying a new size. Quick shipping was nice, but shipping was expensive especially since USPS has priority flat rate.
